What are you even talking about...? You are just spouting out a bunch of random shit that isn't even true. Did you even bother looking up any statistics or are you just telling yourself that is how it works.
Average Games played
Zed: 60
Varus: 23
Zed's player base may be way bigger, but his playe rbase is much more experienced than Varus's player base.
Winrate by games played:
Varus
1-5: 47.33%
5-15: 47.69%
15-50: 53.82%
50-125: 61.03%
125+: 44.22%
Zed
1-5: 47.64%
5-15: 47.12%
15-50: 48.97%
50-125: 51.51%
125+: 54.12%
Now tell me by reading this how exactly you have to be GOOD at Varus to win, but apparently not with Zed? Please do yourself a favor and look up what you are about to post about before saying its a fact. I know you will probably down vote this because I am actually using logic and facts as an argument, but at least do your best to try doing the same in the future :^).
Oh yeah btw Lee never has a high winrate, he is known for being one of the hardest champs in the game and always has a very low winrate, he rarely even passes 50% at 125+ games played.
